It should be appreciated that the present invention can be implemented in numerous ways, including as a process, an apparatus, a system, a device, or a method. Several exemplary embodiments of the invention will now be described in detail with reference to the accompanying drawings.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the present invention.

FIG. 1A is an illustration showing a bluetooth enabled computing system 100, in accordance with one embodiment of the present invention. The system 100 includes a host device 101 defined to include a processor 103 and a memory 105. In various embodiments, the host device 101 can be defined as essentially any type of computing system within which the processor 103 and the memory 105 are defined to collectively execute a computing application. For example, in one embodiment, the host device 101 can be defined as a gaming console, such as the Sony® Playstation 3® entertainment device. In another embodiment, the host device 101 can be defined as a general purpose computing system, such as a desktop, notebook or tablet computer, among others. In yet another embodiment, the host device 101 can be defined as a portable computing device, such as the Playstation Portable device.

The computing application to be executed by the host device 101 can be defined as essentially any type of computer software program that can be compiled in a computer executable form. For example, in one embodiment, the computing application is a gaming program defined primarily for entertainment or educational purposes. In another embodiment, the computing application is a business productivity program, such as a remote conferencing program, a spreadsheet program, a word processing program, a presentation program, a software development program, or a graphics development program, among many others. It should be understood, although particular exemplary embodiments are identified above for the host device 101 and the computing application to be executed thereby, the above-identified exemplary embodiments are not intended to represent an exhaustive set of possible embodiments.

The host device 101 is further defined to include a number of peripheral

device communication ports

107 a, 107 b. Although FIG. 1A shows two exemplary peripheral

device communication ports

107 a, 107 b, it should be understood that the host device 101 can include any number of such peripheral device communication ports. In various embodiments, the peripheral

device communication ports

107 a, 107 b can be defined as essentially any type of communication port, such as a USB (universal serial bus) port, a parallel port, an infrared transceiver port, a radiofrequency transceiver port, or any other type of wired or wireless communication port. Thus, the peripheral

device communication ports

107 a, 107 b are intended to represent any type of communication port defined to enable communication between the host device 101 and a peripheral control device.

By way of the processor 103 and memory 105, the host device 101 is defined to establish a number of

communication channels

109 a, 109 b for a number of

datastreams

111 a, 111 b associated with the executing computer application. Each of the number of

datastreams

111 a, 111 b represents data communicated in either a uni-directional manner or a bi-directional manner between the host device 101 and a

control device

123 a, 123 b. The data communicated between the host device 101 and the

control device

123 a, 123 b can represent either input data received by the host device 101 or output data transmitted by the host device 101. Although FIG. 1A shows two

exemplary communication channels

109 a, 109 b, and two

exemplary datastreams

111 a, 111 b, it should be understood that the host device 101 is defined to establish any number of communication channels for any number of datastreams. Additionally, the number of communication channels (e.g., 109 a, 109 b) and the number of datastreams (e.g., 111 a, 111 b) can be different. For example, in one embodiment, a communication channel may be established by the host device 101 without being specifically associated with a datastream. In another embodiment, a datastream may be established by the host device 101 without being specifically associated with a communication channel.

The

control device

123 a, 123 b can be essentially any type of peripheral device capable of providing input data to the host device 101, and in some embodiments also capable of receiving output data from the host device 101. For example, in one embodiment, the

control device

123 a, 123 b can be defined as a controller or gamepad of a gaming system. In various other embodiments, the

control device

123 a, 123 b can be defined as a keyboard, a keypad, a mouse, a microphone, a speaker, a display, a touchscreen, a video camera, among many others.

FIG. 2 is an illustration showing a controller 200 of a gaming system suitable for use as the control device (e.g., 123 a, 123 b), in accordance with one embodiment of the present invention. The controller 200 can have a variety of buttons including a digital control pad represented by DU, DR, DD and DL. The controller 200 can also have left shoulder buttons 201 a that include LS1 and LS2. Similarly, right shoulder buttons 201 b include RS1 and RS2. Analog sticks AL and AR can be included on the controller 200 where the analog sticks are also capable of acting as buttons when depressed. The controller can also include selection buttons illustrated as a square, a triangle, a circle, and an “X”. The controller 200 can also include a number of LEDs 203. The embodiment of FIG. 2 shows the number of LEDs 203 defined on a top surface of the controller 200. However, other embodiments can have the LEDs 203 defined on a surface of the controller 200 other than the top surface. While particular names and symbols have been used to describe the exemplary controller 200, the names are exemplary and not intended to be limiting.

It should be appreciated that multiple control devices (e.g., 123 a, 123 b) can be associated with a common datastream (e.g., 111 a, 111 b), such that input from each of the multiple control devices is conducted through the common datastream to the host device 101, and output from the host device is conducted through the common datastream to each of the multiple control devices associated therewith. Therefore, although FIG. 1A shows a

single control device

123 a, 123 b associated with each datastream 111 a, 111 b for clarity of description, it should be understood that in various embodiments multiple control devices can be associated with a common datastream.

The host device 101 also includes a bluetooth host chip 113 connected therein to enable establishment of a bluetooth connection 115 with a bluetooth client chip 119 in an external device 117 outside the host device 101, and to enable bluetooth communication over the bluetooth connection 115. The bluetooth host chip 113 is defined to enable registration of the bluetooth client chip 119 and communication with the bluetooth client chip 119, without consuming resources of the host device 101 used to execute the computing application, so as to avoid adversely impacting the performance of the computing application. Registration of the bluetooth client chip 119 with the bluetooth host chip 113 represents a pairing of the bluetooth client and host chips to enable bi-directional bluetooth communication between the bluetooth client chip 119 and the bluetooth host chip 113.

The processor 103 of the host device 101 is further defined to enable connection of the bluetooth client chip 119, by way of the bluetooth host chip 113 and bluetooth connection 115, to one or more selected communication channels (e.g., 109 a, 109 b) such that one or more datastreams (e.g., 111 a, 111 b) associated with the selected communication channels can be monitored by the external device 117. For example, in the embodiment of FIG. 1A, a connection 121 is established within the host device 101 between the bluetooth host chip 113 and the communication channel 109 a such that the datastream 111 a associated with the control device 123 a and the communication channel 109 a can be monitored by the external device 117 over the bluetooth connection 115.

In one embodiment, the host device 101 is defined receive a communication channel selection signal transmitted from the external device 117. The communication channel selection signal is defined to identify one or more communication channels within the host device 101 to which the external device 117 is to be connected, i.e., linked. The processor 103 of the host device 101 is defined to connect the bluetooth client chip 119 in the external device 117, by way of the bluetooth connection 115 and bluetooth host chip 113, to the one or more communication channels identified by the communication channel selection signal.

In one embodiment, the communication channel selection signal is generated and transmitted by the external device 117. In one version of this embodiment, the communication channel selection signal is transmitted over the bluetooth connection 115. In another version of this embodiment, the communication channel selection signal transmitted by another means not associated with the bluetooth connection 115. In another embodiment, the communication channel selection signal is generated and transmitted by a control device (e.g., 123 a, 123 b) connected to the host device 101.

It should be appreciated that in various embodiments, the communication channel selection signal can be generated by either mechanical, auditory, or visual means, then rendered in a format that can be communicated to the host device 101 and processed by the processor 103 within the host device 101. For example, in one embodiment, a button on the external device 117 can be used to generate the communication channel selection signal, the communication channel selection signal can then be rendered in a bluetooth communicatable format, and transmitted via the bluetooth connection 115 to the host device 101. In another exemplary embodiment, a microphone on the external device 117 can be used to generate the communication channel selection signal, the communication channel selection signal can then be rendered in a bluetooth communicatable format, and transmitted via the bluetooth connection 115 to the host device 101. In yet another exemplary embodiment, a button on a control device (e.g., 123 a, 123 b) can be used to generate the communication channel selection signal, the communication channel selection signal can then communicated via an associated datastream (e.g., 111 a, 111 b) to the host device 101.

In one embodiment, the communication channel selection signal is defined to identify a single communication channel established within the host device 101. In one version of this embodiment, the communication channel selection signal is received by the host device 101 as a pulse train defined by a successive number of pulses, wherein the number of successive pulses indicates a number identifier of the communication channel to which the external device 117 is to be connected. For example, as illustrated in FIG. 1B, a communication channel selection signal defined as a pulse train of two successive pulses, having been generated by a double-click of a button by a user of the external device 117, can direct the host device 101 to connect the external device 117 to a second communication channel, such that the external device 117 can monitor one or more datastreams associated with the second communication channel, by way of the bluetooth connection 115. It should be understood that the above-mentioned exemplary embodiments for generating and transmitting the communication channel selection signal to the host device 101 are provided as examples to facilitate description and are not intended to represent an exhaustive set of embodiments for generating and transmitting the communication channel selection signal.

In one embodiment, the processor 103 within the host device 101 is defined to generate and transmit a communication channel selection feedback signal upon connection of the bluetooth client chip 119 of the external device 117 to the communication channel (e.g., 109 a, 109 b) identified by the communication channel selection signal. In various versions of this embodiment, the communication channel selection feedback signal can be either a mechanical signal, an auditory signal, or a visual signal. For example, in one embodiment the communication channel selection feedback signal can be defined as a visual signal shown on a display associated with the host device 101. In another exemplary embodiment, the communication channel selection feedback signal can be conveyed by illuminating a number of LEDs on a control device (e.g., 123 a, 123 b) associated with the communication channel (e.g., 109 a, 109 b) to which the external device 117 is connected, wherein the number of illuminated LEDs indicates the number of the communication channel to which the external device 117 is connected. For example, a number of the LEDs 203 of the exemplary control device 200 shown in the embodiment of FIG. 2 can be illuminated to indicate the number of the communication channel to which the external device 117 is connected.

In yet another embodiment, the communication channel selection feedback signal can be conveyed audibly through a speaker to identify the communication channel (e.g., 109 a, 109 b) to which the external device 117 is connected. The speaker in this embodiment, may be defined in the external device 117, in the control device (e.g., 123 a, 123 b), or as another component connected to the host device 101. In yet another embodiment, the communication channel selection feedback signal can be conveyed mechanically as a vibratory pulse to identify the communication channel (e.g., 109 a, 109 b) to which the external device 117 is connected. The vibratory pulse in this embodiment, may be generated at the external device 117, at the control device (e.g., 123 a, 123 b), or at both the external device and the control device. It should be understood that the above-mentioned exemplary embodiments for generating and transmitting the communication channel selection feedback signal are provided as examples to facilitate description and are not intended to represent an exhaustive set of embodiments for generating and transmitting the communication channel selection feedback signal.

As previously mentioned, in one embodiment, the external device 117 can be connected to simultaneously monitor multiple communication channels.

The reader 940 is also operable to read DVD-ROMs compatible with the Playstation 2 and PlayStation 3 devices, in addition to conventional pre-recorded and recordable DVDs. The reader 940 is further operable to read BD-ROMs compatible with the Playstation 3 device, as well as conventional pre-recorded and recordable Blu-Ray Disks.

The system unit 900 is operable to supply audio and video, either generated or decoded by the Playstation 3 device via the Reality Synthesizer graphics unit 930, through audio and video connectors to a display and sound output device 942 such as a monitor or television set having a display 944 and one or more loudspeakers 946. The audio connectors 950 may include conventional analogue and digital outputs whilst the video connectors 952 may variously include component video, S-video, composite video and one or more High Definition Multimedia Interface (HDMI) outputs. Consequently, video output may be in formats such as PAL or NTSC, or in 720p, 1080i or 1080p high definition.

Audio processing (generation, decoding and so on) is performed by the Cell processor 928. The Playstation 3 device's operating system supports Dolby® 5.1 surround sound, Dolby® Theatre Surround (DTS), and the decoding of 7.1 surround sound from Blu-Ray® disks.

In the present embodiment, the video camera 912 comprises a single charge coupled device (CCD), an LED indicator, and hardware-based real-time data compression and encoding apparatus so that compressed video data may be transmitted in an appropriate format such as an intra-image based MPEG (motion picture expert group) standard for decoding by the system unit 900. The camera LED indicator is arranged to illuminate in response to appropriate control data from the system unit 900, for example to signify adverse lighting conditions. Embodiments of the video camera 912 may variously connect to the system unit 900 via a USB, Bluetooth or Wi-Fi communication port. Embodiments of the video camera may include one or more associated microphones and also be capable of transmitting audio data. In embodiments of the video camera, the CCD may have a resolution suitable for high-definition video capture. In use, images captured by the video camera may for example be incorporated within a game or interpreted as game control inputs.

In general, in order for successful data communication to occur with a peripheral device such as a video camera or remote control via one of the communication ports of the system unit 900, an appropriate piece of software such as a device driver should be provided. Device driver technology is well-known and is not be described in detail herein to avoid unnecessarily obscuring the present invention.

FIG. 8 is a schematic of the Cell processor 928, in accordance with one embodiment of the present invention. The Cell processor 928 has an architecture including four basic components: 1) external input and output structures including a memory controller 1060 and a dual bus interface controller 1070A,B; 2) a main processor referred to as the Power Processing Element 1050; 3) eight co-processors referred to as Synergistic Processing Elements (SPEs) 1010A-H; and 4) a circular data bus connecting the above components referred to as the Element Interconnect Bus 1080. The total floating point performance of the Cell processor is 218 GFLOPS.

The Power Processing Element (PPE) 1050 is based upon a two-way simultaneous multithreading Power 970 compliant PowerPC core (PPU) 1055 running with an internal clock of 3.2 GHz. It comprises a 512 kB level 2 (L2) cache and a 32 kB level 1 (L1) cache. The PPE 1050 is capable of eight single position operations per clock cycle, translating to 25.6 GFLOPs at 3.2 GHz. The primary role of the PPE 1050 is to act as a controller for the Synergistic Processing Elements 1010A-H, which handle most of the computational workload. In operation the PPE 1050 maintains a job queue, scheduling jobs for the Synergistic Processing Elements 1010A-H and monitoring their progress. Consequently, each Synergistic Processing Element 1010A-H runs a kernel whose role is to fetch a job, execute it and synchronizes with the PPE 1050.

Each Synergistic Processing Element (SPE) 1010A-H includes a respective Synergistic Processing Unit (SPU) 1020A-H, and a respective Memory Flow Controller (MFC) 1040A-H including in turn a respective Dynamic Memory Access Controller (DMAC) 1042A-H, a respective Memory Management Unit (MMU) 1044A-H and a bus interface (not shown). Each SPU 1020A-H is a RISC processor clocked at 3.2 GHz and including 256 kB local RAM 1030A-H, expandable in principle to 4 GB. Each SPE gives a theoretical 25.6 GFLOPS of single precision performance. An SPU can operate on 4 single precision floating point members, 4 32-bit numbers, 8 16-bit integers, or 16 8-bit integers in a single clock cycle. In the same clock cycle it can also perform a memory operation. The SPU 1020A-H does not directly access the system memory XDRAM 926. The 64-bit addresses formed by the SPU 1020A-H are passed to the MFC 1040A-H which instructs its DMA controller 1042A-H to access memory via the Element Interconnect Bus 1080 and the memory controller 1060.

The Element Interconnect Bus (EIB) 1080 is a logically circular communication bus internal to the Cell processor 928 which connects the above processor elements, namely the PPE 1050, the memory controller 1060, the dual bus interface 1070A,B and the 8 SPEs 1010A-H, totaling 12 participants. Participants can simultaneously read and write to the bus at a rate of 8 bytes per clock cycle. As noted previously, each SPE 1010A-H comprises a DMAC 1042A-H for scheduling longer read or write sequences. The EIB comprises four channels, two each in clockwise and anti-clockwise directions. Consequently, for twelve participants, the longest step-wise data-flow between any two participants is six steps in the appropriate direction. The theoretical peak instantaneous EIB bandwidth for 12 slots is therefore 96 B per clock, in the event of full utilization through arbitration between participants. This equates to a theoretical peak bandwidth of 307.2 GB/s (gigabytes per second) at a clock rate of 3.2 GHz.

The memory controller 1060 comprises an XDRAM interface 1062, developed by Rambus Incorporated. The memory controller interfaces with the Rambus XDRAM 926 with a theoretical peak bandwidth of 25.6 GB/s. The dual bus interface 1070A,B comprises a Rambus FlexIO® system interface 1072A,B. The interface is organized into 12 channels each being 8 bits wide, with five paths being inbound and seven outbound. This provides a theoretical peak bandwidth of 62.4 GB/s (36.4 GB/s outbound, 26 GB/s inbound) between the Cell processor and the I/O Bridge 700 via controller 170A and the Reality Simulator graphics unit 200 via controller 170B. Data sent by the Cell processor 928 to the Reality Simulator graphics unit 930 will typically comprise display lists, being a sequence of commands to draw vertices, apply textures to polygons, specify lighting conditions, and so on.
